Walnut Avenue between 29th and Spring streets in Signal Hill has been closed to traffic as crews work to clean up 25 barrels of oil that leaked from a pipeline on Wednesday, county fire officials said.

Los Angeles County Fire Department spokesman Gustavo Medina said crews were dispatched to the 1500 block of Spring Street at 4:03 p.m. The spill has since been contained, he said, and a pump truck is on scene cleaning it up.
